New board: MonSTer

[joska]

They must be removed, otherwise you will be booting from two sets of ROMs at the same time.

sweet, I've spared myself some STE mods

Thanks Jo Even, this update is much appreciated
I hope to find the time to check it out in detail the upcoming weekend.

I did indeed take out the socketed TOS ROMS from my STe, but when I installed the MonSTer in the MegaST I simply forgot to do that - and for some reason that seems to work fine, it boots without complaints from the ROM images flashed into the MonSTer. I suppose it might be better to take the ROMs out anyways but so far I have not detected any unwanted side effects.

When the images match, it's likely to not cause a problem because the data is the same.

It's when you've flashed a modified TOS that problems will occur.

You could put a switch on the OE/CE pin on the originals ROMs and leave them in though for when you'd need a failsafe.

And if you use a DPDT switch you can switch in the motherboard ROMs and the FLASHON jumper at the same time, giving you one extra TOS.

Not absolutely related to MonSTer but related.

I also have (bought not installed) Exxos accelerator (STE accelerator@32MHz). Can that be combined with MonSTer?

It's years since I've used my ST but I think the 1.04 ROMS are soldered so having a switch would be useful.

Mine has a T-board 2.06 ROM upgrade in it with a socket soldered onto the 68000 at an angle to clear the keyboard.

It's tempting to do some upgrades but I'm not sure if it would get much use.

I don't know this accelerator, but I assume exxos would know if it has been tested with a MonSTer. I have an earlier accelerator from exxos (16MHz), and that one does *not* work with MonSTer.

[MegaSTEarian]

He said he does not know if it's going to work.

The idea is: Exxos accelerator need CPU carrier desoldered and after a few tweaks to solder in the accelerator carrier. I was wondering, since MonSTer has a CPU relocator, that maybe that could be used instead.

Looks like it needs it's own ROM board, so I doubt it will work with MonSTer.

[DarkLord]

Lots of accelerator's seem to have problems with the MonSTer.

The AdSpeed in my Mega ST4, for example.

[joska]

The problem with AdSpeed is that it's control registers are at the exact same addresses as the IDE-port. So AdSpeed does not work with any Atari with IDE-interface.

[DarkLord]

Correct me if I'm wrong but it wasn't just the AdSpeed, right? (I guess they all
broke the rules and used those addresses).
